Welcome

 

Lertap5 is now perpetually unlocked.

 

What has been known as the "Mini version", with a limit of 250 data records, is gone. There is no longer a limit on the number of data records which may be processed without having to buy what was called an "unlock code" with its corresponding license.

 

Got a computer equipped with Excel and some test or survey item responses to process? If so you're ready to go. Click here to visit the Lertap5 downloads link. You'll get a "zip" file containing Lertap5.xlsm and a variety of supporting documents.
